  1. Which country has definitively purchased the maximum number of COVID vaccine doses?

  2. Which country is speculated to have contained the maximum number of CODID vaccine doses?

  3. The total population of the USA is approximately 328 million. If the USA contains 2.6 billion vaccine doses, how many times can it vaccinate its population, if most COVID vaccines require individuals to take two doses to protect themselves from the virus?
